Summary
-------

Occasionally there is a need to put all objects in one container also into another container.

Some reasons you might need to do this:
1) You need to reconfigure a container.   You would do this by creating a new container with the new configuration and ao2_container_dup the old container into it.  Then replace the old container with the new.  Then destroy the old container.

2) You need the contents of a container to remain stable while operating on all of the objects.  You would do this by creating a cloned container of the original with ao2_container_clone.  The cloned container is a snapshot of the objects at the time of the cloning.  When done, just destroy the cloned container.

Testing
-------

Added unit testing code to test the new ao2_container_clone and ao2_container_dup functions.

Tests still pass.
